D.J. Morgan sustained a turf toe injury during player-only workouts and is wearing a protective boot to expedite healing, according to FoxSportsWest.com.

The injury is especially disconcerting because it further exposes the lack of depth on the Trojans’ roster at certain positions. This week, defensive end Devon Kennard, a projected starter, confirmed he suffered a torn pectoral muscle in the weight room and could be lost for the season after he undergoes surgery.

Morgan did not hint at surgery in his future, but even the slightest setback is trouble. Meanwhile, Penn State running back Silas Redd was expected on the USC campus Saturday on an NCAA-sanctioned recruiting trip.

He is expected to make a decision by Monday.

“We were competing in the Coliseum on the stairs and I hyperextended my toe and so (I’ve) just been trying to cater to it so I’m making sure I’m percent come camp,” Morgan told FoxSportsWest.com. USC begins camp Aug. 6. “They have me in a boot right now. I went to see the foot specialist. He said it’s nothing major. Nothing’s fractured or anything. I just have to stay off of it for a little while.”

Morgan said his toe is bruised and tender.

He and Curtis McNeal are the only current USC running backs with any experience. Incoming freshman Nelson Agholor is moving from receiver to running back to provide depth there as well.
